Description
MSP430FW423IPMR is a Texas Instruments MSP430 microcontroller, part of the FW423 family. It’s a 16‑bit RISC MCU designed for ultra‑low‑power operation in battery‑powered sensing and control tasks. The FW423 designation identifies the specific device in the FW42x family, while the IPMR suffix is TI’s packaging/variant code for this part (verify exact package/temperature in the datasheet).
Key features you’ll typically find on FW42x devices: on‑chip Flash for program memory and RAM; multiple low‑power operating modes; peripherals such as ADC (and general purpose timers); serial communication interfaces (UART/USCI/eUSCI, I2C, SPI); GPIO; watchdog timer; and DMA options; clock sources including DCO and optional crystal.
For exact memory size, I/O count, peripheral set, package, and electrical specs, consult the MSP430FW423IPMR datasheet and user guide. Use Code Composer Studio or IAR for development, and review the device errata.
